(Cl. 24d-2) 2 Claims.

The invention relates to improvements in a service creeper transporthaving a border structure for the protection and insulation of multiplesegregated artificial lighting elements, to assist the visualizing ofobjects to be viewed, and to prevent the glare of light from interferingwith the workmans vision during manually operative control.

Stating the nature of the case generally and as is evident from ageneral inspection of the drawing, the invention relates to that-category of structures grouped under the classification of workmansgarage Creepers and has for its primary object means provided toapproximately surround the creeper and operator with multiple articiallighting elements submerged in a structure below the sides and to therear of the workmans visual focus, pending operative control when theoperator is rendering service in a lieing position on said creeper.

A further object of my invention is to provide a semi-cylindricaltransparent insert that will cover, protect and transmit rays producedby the lighting elements, by the placing of and forming a transparentflexible plastic material between a top and a bottom layer of mesh Wire.

Another object of my invention is to provide a reflector submergedadjacent to lighting elements, to enclose light area and to assist thelight rays to be transmitted through a transparent plastic insert,including a means for transmitting air through said reector.

A still further object of my invention is to provide a sectional conduitcomposed of adjacent members that provide means for insulation andprotection of segregated lighting elements, including means fordismounting a section of said conduit pending the renewing of disabledparts.

Another object of my invention is to provide means for a cooling andVentilating gravity air flow through composed openings to dismiss heatproduced by the lighting elements.

With the above and other objects in view to appear hereafter myinvention consists in the novel features of construction of parts to behereinafter described and more particularly pointed out in the subjoinedclaims.

Refer to the drawing:

l Figure 1 is a perspective View of my improved portable illuminatingdevice.

Figure 2 is an explanatory detail arrangement showing the fabricating ofparts.

Figure 3 is a cross section detail showing the position of bed, castorsand the end of border structure.

Figure 4 is a perspective of a Creeper elongated bed.

Figure 5 is a detail of channel insert that coincides with a recessformed in a side member to form a conduit extending around the remoteperimeter of a Creeper border structure.

Referring to the drawing in detail the Creeper border structure embodiesside members 9 and I3 which are attached to the bedl I by means of boltsor screws 22.

Side members 9 and I8 respectively have their ends 4 connected to anelongated channel member 23 in any suitable and well known manner,including the step of fabricating a like narrow channel member 23 asaforesaid to support side members 9 and I8 at intervals throughoutlighting area, the same said narrow channel member 23 form a seat forinsert members 6.

A reflector l2 is positioned subjacent the lighting elements, supportedby the bed l and members 9 and l 8 including the step of providingopenings |4 for air to pass through.

I place within the border like structure Figure 2 light bulbs 'linserted in receptacles of the two piece screw lock type assembled inholes i3, the Wires Within a current conducting cord l5 are assembled inconduit 3 and 2| and are attached to said receptacles. The cord may beof any desired length and has means for connecting with a plug, socketor the like located in any suitable place so that current will'besupplied to the electric bulbs or other lighting elements whenever thedevice is placed in use. The means of connecting the electric cord tothe light bulbs 'I or such artificial lighting elements will of coursebe apparent and requires no particular illustration or explanation.

The lighting elements I will create considerable heat within thestructure 223, for this reason I have arranged composed air openings ll,l l and Hi in side members 9 and I3 and in reflector I2 to create agravity air circulation, for the escape of the heat produced within thestructure 20.

In the particular arrangement shown it will of course be apparent thatmeans be provided to transmit the light from Within and protect thelighting elements from without, to protect said lighting elements and totransmit said light. Elements 6 and 8 form light transmitting protectioncovers, composed of a transparent nexble plastic material 8, formedbetween a top and a bottom ply of mesh wire 6.

For transmitting electric current to said creeper, a suitable extensionplugin means is attached to receptacle I'I, and wiring I5. A circuitbreaker switch I6, turns off the lighting means 1.

The creeper as a whole Fig. 1 is supported by multiple swivel-casters 2,which revolve in clearance openings I9.

Channel members 4 provide storage space for tool and parts pans 5.

A worlcmans head-rest 24 is attached to the creeper bed I in anysuitable manner.

In Fig. 5, the top and bottom sides of channel 3 have lugs Ill- I0formed at intervals, providing means for attaching said channel member 3to side members Iii-I8, to provide a de-v tachable sectional conduit.

Having thus described my invention what I claim is:

1. A mechanics creeper of the character described comprising: a hollowupstanding border structure about two sides and one end of the creeper,said hollow border structure having a plurality of light transmittingopenings in the top side thereof, a plurality of light sources mountedrin said hollow border structure below said openings, and a. lighttransmitting protective cover mounted over each of said openings.

2. A mechanics creeper of the character described comprising: a hollowupstanding border structure about two sides of the creeper, said hollowborder structure having a plurality of light transmitting openings inthe top side thereof. a plurality of light sources mounted in saidhollow border structure below said openings, and a light transmittingprotective cover mounted over each of said openings.

JOI-IN AUGUSTUS MCCARTHY.
